Speaker Front left, Front high left, Zone 2 left Front right, Front high right, Zone 2 right Center Surround left Surround right Surround back left Surround back right Color White Red Green Blue Gray Brown Tan The supplied speaker cable labels are also color-coded and you should attach them to the positive (+) side of each speaker cable in accordance with the table above. Then all you need to do is to match the color of each label to the corresponding speaker terminal. • Be careful not to short the positive and negative wires. Doing so may damage the AV receiver. • Make sure the metal core of the wire does not have contact with the AV receiver's rear panel. Doing so may damage the AV receiver. Connections • Don't connect more than one cable to each speaker terminal. Doing so may damage the AV receiver. • Don't connect one speaker to several terminals. Speaker Connection Precautions Read the following before connecting your speakers: • You can connect speakers with an impedance of between 6 and 16 ohms. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp protection circuit may be activated. • Disconnect the power cord from the wall outlet before making any connections. • Read the instructions supplied with your speakers. • Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals only to positive (+) terminals, and negative (-) terminals only to negative (-) terminals. If you get them the wrong way around, the sound will be out of phase and will sound unnatural. • Unnecessarily long, or very thin speaker cables may affect the sound quality and should be avoided.
